SnakePanel类

主类 Snack类

package game.snake.first_try; import javax.swing.JFrame; public class Snake { public static void main(String[] args) { JFrame frame = new JFrame(); frame.setBounds(550, 200, 950, 750); //边界 frame.setTitle("贪吃蛇1.0"); //标题 frame.setResizable(false); //能否改变大小 frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); //退出方式frame.add(new SnakePanel()); frame.setVisible(true); }}

尾言 【贪吃蛇（定时器控制）】其实，定时器版和双缓冲版对这个版本的贪吃蛇作用并不大，或者说没有作用。主要还是因为，他的坐标是25的加的，即使他的加载很流畅，但是因为每次都是25的跨度，所以还是会有闪烁。不过这次经历确实给了我很多东西，还算不错。人生不止，代码不断。?加油！
